MECHANICAL MUSICAL INSTRUMENT.

Appicaticn filed Sepcmher 2E), (No model.)

To all whom it may concern:

Be it known that I, MAMERT Hooit, a citizenof Germany, and a resident of Saar Louis, in Germany, have invented a new and useful Improvement in Perforated Music Sheets or Bands for Musical Instruments, of which the following is a specification.

In mechanical musical instruments dii'ficulty is experienced with the perforated music sheets or bands through which the opening of the reeds is regulated, partly on count of their inefliciency to contain very long pieces of music and partly on account of the difficulty of unwinding these sheets or bands regularly from their respective drums.

The nature of my invention consists in the arrangement of a spiral-shaped sheet or band in which the usual and necessary perforations are made, constructed similarly to the blades of a screw, lying one above the other, and which sheet, while receiving a regular rotating motion, passes gradually into the ease of the instrument and over the levers, which, by their working into and out of the perforations, operate the valves of the reeds in the desired manner.

111 the accompanying drawings, Figure I represents a section of part of the instrument embodying my invention. Fig. II is a top view of the same. Fig. III is a section of the instrument with wheel K partlybroken away, showing a different plan of turning the spiral musicsheet. Fig. IV is a horizontal section at line A B, Fig. III, showing the position of the reed-valves. Fig. V is a side view of the machine represented in Fig. III. Fig. VI is a top View of the same; and Figs. VII and VIII represent a side view and plan of the spiral music bands or sheets at an enlarged scale.

Similar letters represent similar parts in all the figures.

0 represents the case of the instrument, in the lower part of which the reed-valves i) 'u, constructed in the usual manner, are arranged on one side of the box, as shown in Fig. IV. Below the reed-valves the usual bellows, D, are arranged, operated from a crank, d, in the shaft S.

h 71/ are levers to operate the reed-valves r.

E is a box inside the case to receive the music-sheet after the same has passed the lovers h and passed into the casing.

F is the cover of the case, having a central opening for the shaft G to pass through to its end support, attached to the under side of the cover F. The upper end of the shaft or stand G supports the end of the horizontal shaft S, provided with a crank, d, for operating the bellows D, and with a pinion, b, meshinginto suitable teeth or projections on the wheel K, turning freely on the shaft or stand G.

L is a crank for operating the shaft S.

M is the music sheet or band, shaped spirally, similar to a screwblade, having a central opening, N, for the shaft or stand G to pass through. This music-sheet M is formed of any required number of disks of the desired diameter and the necessary central hole, N. These disks are cut through at one part, I), where the edge a of the lower disk is jointed to the edge a of the upper disk until the required length of music. sheet is obtained, whereby a regular spiral band or sheet will be obtained. This sheet or band M is provided with the necessary perforations,a, correspond ing with the music to be played, made in the usual manner. Near the central opening, N, holes 6, Fig. VIII, are arranged, into which the carrying-pins m. attached to the under side of the wheel K, tit, and by means of which this coil of the music sheet or band is turned around by the movement of said wheel K. In the cover F a longitudinal slit or opening, I, is made, througlrwhichthe music-band passes from. the outside into the box E. This spirally-shaped music-sheet M is placed between the cover Fand the under side of the wheel K, and made to enter through the slit or opening I, passing on the inside over the projecting points 00 of the lever 7L, which, while passing into and out of the perforations a made in the spiral-shaped music-sheet liI, operate the reedvalves 1) in the usual manner.

To assist the regular laying of the spiral music-sheet in the box E, the shaft G may be made to turn with the wheel K and pass downward to the bottom of the box IE, and be provided with a disk-plate, It, upon which the spiral music-sheet collects and will lay itself in the regular spiral shape upon the same, said disk-plate It revolving at the same speed and receiving the same as fast as blade after and for the purpose described. blade is unwound, and passes through the slit 2.
